| Description: | ||||
Downloaded tcl9.0b3 gz tarball from sourceforge. Did a generic configure on Alpine Linux v3.20 and tried a source build. During build, errors at this point:
/home/mack/src/tcltk/tcl9.0b3/unix/tclEpollNotfy.c:28:10: fatal error: sys/queue.h: No such file or directory
28 | #include <sys/queue.h>
| ^~~~~~~~~~~~~
compilation terminated.
Looks like a new dependency on queue.h which does exist on alpine.
Tcl version: 8.6.14 builds without any problems.
Thank you,

as a workaround, I just copied the netbsd version of queue.h file into the compat directory and changed the sys/queue.h to ../compat/queue.h for now. jan.nijtmans added on 2024-08-07 16:51:52:
I think you will find your answer here. apk add --no-cache bsd-compat-headers Hope this helps, Jan Nijtmans danmack42 added on 2024-08-07 17:35:10:
thank you, that's it. appreciate your help. dan oehhar added on 2024-08-07 19:11:38:
Would it be helpful to add this information into the TCL migration guide or release notes? Or is this a general purpose problem and not related to TCL? Should "configure" detect this? Thanks, Harald serhiy.storchaka added on 2026-10-20 13:07:22:
As Harald asked, Tcl itself can avoid this: tclEpollNotfy.c only needs six list macros from <sys/queue.h>, which musl does not provide. Proposed fix in branch epoll-no-sys-queue: define them in tclEpollNotfy.c instead of including that header, so no configure check and no bsd-compat-headers are needed. Tested on Alpine 3.24 without bsd-compat-headers: the current main fails as reported, with the branch it builds and the event, socket, I/O and notifier tests pass; also tested on Linux with glibc. oehhar added on 2026-10-20 13:29:32:
Great. The preprocessor gymnastics feel good. It would be ok for me to merge. Thanks, Harald jan.nijtmans added on 2026-10-20 21:28:33:
